Remote Control FM Stereo Radio

Nowadays, FM radio frequency had already become common for communication use. It use for data transfer, Medical treatment, cosmetic treatment and more. Radio frequency (RF) is a rate of oscillation in the range of around 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals. Today, we are going to experience the common FM radio freq, BUT, not by using the big radio. We are going to use a single-chip electronically tuned FM stereo radio which is TEA57657 with some support components. To ease user from headache to collect all the support components, we had come out FR02A!!

Since we are using the IR Remote, It will be much easier to use back the library provided. In this tutorial, I had connect the IR Received signal pin (RECV_PIN) to Arduino Digital Pin 2. And the NPN Base to Digital Pin 3.

In this part, Check the IR Receiver if it receive any signal and decode it. Below are the Hex and Decimal number for the button that use in this project. In order to identify each button Hex/DEC, load the IRrecvDemo.ino to identify.
